It looks like NBC brass have figured out a way to take full advantage of Jimmy Fallon’s stellar ratings over on the new Tonight Show, if the following rumor is true. TMZ reports that NBC is allegedly pressuring celebrities who want to be on The Tonight Show against appearing on other networks’ late night talk shows and even morning shows as well, the only exception being NBC shows like Dateline, Today, and Late Night: “They put the word out to celebs, agents and publicists … if they want to be on Fallon they can’t appear on ANY other network … and not just shows that go head-to-head with Jimmy, but morning shows as well.” A source from Good Morning America claimed that they’ve already gotten fallout from recent Tonight Show guests they attempted to book, so the rumored plan is already in motion. Fallon’s ratings have blown Leno’s entire era out of the water, and The Tonight Show currently brings in two times the amount of viewers as Jimmy Kimmel Live!, but if NBC is really threatening celebrities and their publicists against going on any other show, those numbers might end up inflating even more over the next few months.
